International consensus principles for the sustainable harvest of polar bears.

Multilateral agreements are required for the effective management of large carnivores with ranges that cross geopolitical boundaries. This is particularly important for species subject to rapid changes in distribution or demographic status due to climate warming. We considered 3 international consensus principles for the sustainable harvest of polar bears (Ursus maritimus), a circumpolar species threatened by sea-ice loss and harvested by Indigenous Peoples for subsistence.

Effect of involving physiotherapists in the management of low back pain at emergency departments: a systematic review.

Objectives: To conduct a systematic review investigating the effects of physiotherapy in emergency departments (EDs) on health care use and patient-reported outcomes for patients referred to EDs due to low back pain (LBP), compared with usual care.

Methods: A search was conducted in PubMed, Cinahl and Embase in April 2023, and rerun in September 2024. Randomised and quasi-randomised trials and observational studies including adult patients referred to an ED due to LBP were eligible.

Project symphony: Composing a masterpiece in a science laboratory.

In the spirit of collaborative science, Prof. Sunghee Lee (Chemistry Professor at Iona University in New York, USA) embarked on her academic career with a vision to bring an interdisciplinary approach to undergraduate education. At a Predominantly Undergraduate Institution (PUI) such as Iona, she saw a unique opportunity to weave together teaching and research, creating a rich tapestry of learning experiences for students.

Model sensitivity limits attribution of greenhouse gas emissions to polar bear demographic rates.

Greenhouse gas emissions continue to increase and negatively affect sea ice conditions that polar bears rely on. It is therefore important to better understand how specific emissions levels affect polar bear demography. A recent study proposed a framework to address this issue, but sensitivity to decisions rules of the approach may limit its utility.

Fecundities of Hawaiian wild strains are not correlated with natural niche temperatures.

Adaptation to the local environment is crucial for organisms to survive and reproduce in the natural niche. The nematode has been studied extensively and hypothesized to be adapted to temperatures at the geographic sites where nematodes were isolated from nature. We empirically tested if this correlation is biologically meaningful by measuring the fitness of wild strains isolated from different temperatures across the Hawaiian islands.
